08 SHO noise

My SHO has around 9 hours on it. I just took it out of winterization and it fired right up. Problem is a noise I hear that wasn't there when I Stored it. After I shut it down I hear something winding down, like a worn out bearing still rolling. I thought it was the starter, but after the shop looked at it they said it wasn't the starter and it was a normal noise that all the SHOs do after they are broke in?????
Anyone else hear anything after the ski is shut down?
Just want to know if this really is normal.
